Slide the mini rubber band onto the long popsicle stick and place in the middle.

Wrap the pipe cleaner around both ends as seen in picture below.

Place binder clips over both ends of the pipe cleaner to secure.

Place clothespin on Biggie Bead.

Discuss with students how to make their scale balance (hang equal) by keeping the bead/clothespin over the rubber band.

Use suggested objects below to weigh.

(affiliate ads are included in this post to help show the items used in this project)

Place a round magnetic black disc (see link below) on front and back of binder clips. Have your students compare sighing paperclips and magnetic discs. Give your students play dough and let them create different shapes to weigh. Use linking chains, plastic spoons, crayons and other items to weigh too.

Want to Do More?

Recycle Starbucks lids or small cups and use to weigh other objects.

1. Hole punch lids in four different places.
2. Attach pipe cleaner through one hole and string through binder clip
3. Attach the pipe cleaner in the opposite hole and secure.
4. Repeat steps with 2nd pipe cleaner.
5. Follow the same directions for the other side of the scale.

Let the weighing fun begin!

Next Generation Science Standards:

Structure and Function - The shape and stability of structures of natural and designed objects are related to their function.

Develop a simple model based on evidence to represent a proposed object or tool.

Math Standards:

Describe measurable attributes of objects, such as length or weight.

Directly compare two objects with a measure attribute in common, to see which objects has "more of"/"less of" the attribute. For example, which objects weighs more.
